There can be 2 scenarios.
scenario #1
when field1 and field2 are keys on dbfile or keys of LF on
dbfiles
1. Start the DB file with field1 and field2.
2. Read the DB file next record and increase the counter
value.
3. End the process, when end of file reached.
4. if the counter value is greater than zero then move the
counter value to Copybook field else move zeros to the
copybook fields.
scenario #2
when field1 and field2 are not keys on dbfile or not part
of keys of any LF on dbfiles
1.Read the file
2.If the field1 = WS-VAR and Field2 = WS-USERID then
increase the counter
value.
3. End the process, when end of file reached.
4. if the counter value is greater than zero then move the
counter value to Copybook field else move zeros to the
copybook fields.
